Abstract (en)

[origin: US5006621A] Copolymers of long-chain alkyl acrylates or methacrylates of the formula CH2=CR1-CO-OR2 (I) in which R1 is a hydrogen atom or a methyl group and OR2 is a fatty alcohol radical with 16 to 34 carbon atoms and nitrogen-containing olefins can be used as flow improvers for crude oils.

Abstract (de)

Copolymere von langkettigen Alkylacrylaten der Formel CH2=CR¹-CO-OR² (I) in der R¹ ein Wasserstoffatom oder eine Methylgruppe und R² der Rest eines Fettalkohols mit 16 bis 34 Kohlenstoffatomen ist, mit N-haltigen, Acrylat- bzw. Methacrylatfunktionen enthaltenden Olefinen lassen sich als Fließverbesserer für Rohöle einsetzen.
